You have a $350 1984 318i. What Engine swap do you do? M50/52-M20-M30

S50

You guys are confusing competitive with fast. An m10 e30 will rule h street and f street prepared autocrossing. swap it and you end up in street mod where you will get your ass kicked by s2ks. Same applies with road racing. M10 puts you upper mid pack in ITB while swap puts you at the back of STU/STO/SPO. If competition isn't what your after, Then get a manifold from GnT and boost it. Nothing responds better than M10/M30 engines for boost.

After you take care of any maintenance items that need to be done, my vote goes to an M52.

S5x. Same swap work as an M motor but much more possibilities.

No swap, because this is R3V and you just spent your last $350..

Unfortunately, people like the idea and image of being a racer than actually being one. :)
